{{Main|Port Chicago disaster}}

The [[munition]]s on board a [[United States|Navy]] cargo ship exploded while being loaded during [[World War II]], resulting in the largest number of casualties among [[African American]]s in any one incident during that war. On the evening of July 17, 1944, a massive explosion instantly killed 320 sailors, merchant seamen, and civilians working at the pier. The blast was felt {{convert|30|mi|km}} away. A subsequent refusal by 258 black sailors to load any more ammunition was the beginning of the Navy's largest-ever mutiny trial, in which 50 men were found guilty. Future Supreme Court Justice [[Thurgood Marshall]] sat in on most of the proceedings and declared that he saw a prejudiced court.<ref>{{cite book |last = Allen |first = Robert L. |year = 2006 |title = The Port Chicago Mutiny |publisher = [[Heyday Books]] |location = [[Berkeley, California|Berkeley, CA]] |isbn = 978-1-59714-028-7 |oclc = 63179024 |page = 118 |url = https://books.google.com/books?id=2jl6cyAy6u8C |access-date = April 10, 2016 }}</ref>
